Flashing MKS DLC32 MAX - no response after RST

[axife]

Hi, I got into trouble flashing MKS DLC32 MAX

I did

python -m esptool --chip esp32s3 -b 460800 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size 8MB \
    --flash_freq 40m \
    0x0 ~/Downloads/firmware/bootloader.bin \
    0x8000 ~/Downloads/firmware/partitions.bin \
    0x10000 ~/Downloads/firmware/firmware.bin

GRBLHal firmware made with WebBuilder.

So I guess it flashes. But I get no response after doing that.
If I connect with mincom and type $$. I guess nothing.

Do I miss something? Is it known issue?

I could be that MKS has been too lazy to implement native USB comms in their firmware and still uses a USB <> UART chip?
I do not have a board or access to the schematic so I do not know, if you have not tried yet try a build with (Virtual) UART selected:

Is this working?
